2 Filesystems

David Roundy's combination of a nice DarcsIO-style filesystem interface on the Haskell side (called FuseIO) with an interface to libfuse (which is a library for creating filesystems from user space on linux).

4 Processes

Process is a fun library for easing decomposition of algorithms to several processes, which transmit intermediate data via Unix-like pipes. Each sub-process is just a function started with forkIO/forkOS with one additional parameter-pipe.

5 Environment

This module provides an advanced option parsing routine which can properly parse options depending on what types are infered for them as well as produce a pretty error message with usage info when an incorrect option is used.

6 Time

TimeLib is an attempt to redesign the current library for handling time (System.Time), balancing expressive functionality and intelligible simplicity. Now at version 0.2, TimeLib features representation of TAI, UTC and UT1, as well as Gregorian, ISO 8601 week, and "year and day" calendars, time-zones, and functions for strftime-style formatting.

7 Shell

7.1 Link collections on pure functional shells

7.2 Haskell shell examples

A library for using Haskell for tasks which are usually done by shell scripts, e.g. command line parsing, analysing paths, etc. It can be used also for tasks usually done GetOpt (a module for GNU-/POSIX-like option handling of commandline arguments). But also for many other things.

8 Shell utilities

h4sh provides a set of Haskell List functions as normal unix shell commands. This allows us to use Haskell in shell scripts transparently. Each program is generated from the corresponding Haskell function's type

9 Package Management

10 File utilities

magic-haskell is a binding to the libmagic library. With magic-haskell, you can determine the type of a file by looking at its contents rather than its name. This library also can yield the MIME type of a file by looking at its contents.
